OC.05.5 CANCER INVADING THE SUBMUCOSAL LAYER: IS IT TIME TO CHANGE SURGICAL INDICATIONS FOR SCREENING COLONOSCOPIES?

Computer modeling of the wrist has followed other fields in the search for descriptive methods to understand the biomechanics of injury. Using patient-specific 3D computer models, we may better understand the biomechanics of wrist fractures in order to plan better care. We may better estimate fracture morphology and stability and evaluate surgical indications, design more adequate or effective surgical approaches and develop novel methods of therapy. The purpose of this review is to question the actual advances made in the understanding of wrist fractures using computer models.

Objective This study was performed to evaluate the surgical indications, clinical efficacy, and preliminary experiences of nonstructural bone grafts for lumbar tuberculosis (TB). Methods Thirty-four patients with lumbar TB who were treated with nonstructural bone grafts were retrospectively assessed. The operative time, operative blood loss, hospital stay, bone graft fusion time, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) concentration, visual analog scale (VAS) score, Oswestry Disability Index (ODI), American Spinal Injury Association (ASIA) impairment grade, and Cobb angle were recorded and analyzed. Results The mean operative time, operative blood loss, hospital stay, Cobb angle correction, and Cobb angle loss were 192.59 ± 42.16 minutes, 385.29 ± 251.82 mL, 14.91 ± 5.06 days, 9.02° ± 3.16°, and 5.54° ± 1.09°, respectively. During the mean follow-up of 27.53 ± 8.90 months, significant improvements were observed in the ESR, CRP concentration, VAS score, ODI, and ASIA grade. The mean bone graft fusion time was 5.15 ± 1.13 months. Three complications occurred, and all were cured after active treatment. Conclusions Nonstructural bone grafts may achieve satisfactory clinical efficacy for appropriately selected patients with lumbar TB.

Submucosal Dissection

Abstract Background We sometimes experience cases of cervical esophageal cancer which requires laryngectomy due to spread of cancer to larynx. We report a case of esophageal cancer resection with preservation of larynx using intraoperative endoscopic submucosal dissection. Methods The patient was a 59-year-old woman who had dysphagia. She had received total gastrectomy with Roux-en-Y reconstruction for gastric cancer in 2001, chemoradiation (61.2Gy) for esophageal cancer in 2008. Argon plasma coagulation (APC) was performed for the carcinoma in situ of cervical esophagus in 2016. This time superficial 0-IIc tumor was observed at the same site of the scar of APC, and a biopsy revealed squamous cell carcinoma. An endoscopic findings revealed two 0-IIc lesions at distance of 18–22 cm, and 32–34 cm from the incisors, and biopsy resulted in a diagnosis of squamous cell carcinoma. Since tumor was close to the esophageal orifice, the tumor invasion to the larynx was suspected. On the other hand, there were no obvious findings of the submucosal layer invasion, and the both tumor were thought to be limited to the epithelium or lamina propria mucosae (EP/LPM). We performed mediastinoscopic and thoracoscopic transhiatal esophagectomy, subcutaneous ileocolic reconstruction. Results After confirming the tumor invasion to the esophageal orifice by chromoendoscopy with 1% Lugol's iodine solution, we dissected the whole circumference of esophagus in submucosal layer just above the tumor by ESD, put an incision outside of esophageal wall, and resected the esophagus. We preserved short length of muscle layer and performed reconstruction with hypopharynx-ileum anastomosis. Pathological examination revealed squamous cell carcinoma, pT1a-EP, ly0, v0, pPM0, pDM0, pIM0, and curative resection was performed. The postoperative course was uneventful. Conclusion There were no reports of successful larynx-preserving surgery for cervical esophageal cancer using intraoperative ESD. When the tumor was limited in the mucosa, esophagectomy with intraoperative ESD may enable larynx preservation even if the tumor invaded to the esophageal orifice.
